ECAS is the European Commission Authentication Service. It allows users to access a wide range of Commission information systems, using a single username and password. Once you log in, ECAS will remember you as long as you keep your browser open. During that time, you won't have to identify yourself again, no matter how many online services of the Commission you access.
The "Where are you from?" screen (WAYF) is the starting point of an ECAS authentication. Its purpose is to have you choose your authentication domain, which roughly corresponds to the organisation where you have an account. Once this choice has been made, you can log in to ECAS for the selected domain.
The following might help you choose the correct authentication domain:
|If you are...||- additional examples -||... you must choose|
|Commission staff||Commission officials, In-house consultants, trainees||European Commission|
|Executive Agency staff||European Commission|
|A user with a special w+7 account||w1234567||w+7 (= European Commission)|
|Staff from eligible European Institutions and bodies||[your institution]|
|A citizen using information systems of the European Commission||Partners in EU policy making, beneficiaries of EU research grants, journalists subscribing to EU press releases, etc.||External|
Before ECAS can authenticate you as a user, it needs to know in which authentication domain (European Commission, External, etc.) your user account exists. This works best if you provide the information yourself, which is what the WAYF screen allows you to do.
No. Any solution for autodetection of a user's authentication domain (including using their e mail address) would have to work for all types of ECAS users. Currently there is no way to autodetect user accounts that are hosted in a different system and shared with ECAS on a mutual trust basis.
When you select an authentication domain, it is stored as a cookie in your browser. Every time you access ECAS after that, the stored domain setting will be used automatically. As long as you access ECAS using the same PC and the same browser, the WAYF screen will no longer be displayed.
First verify whether your institution or body is included under another, broader authentication domain. Example: Executive Agencies fall under the European Commission domain. If this is not the case and you see no evidence that your institution is supported by ECAS, it is very likely that there is no partnership agreement between the two. This simply means that no ECAS account has been created for you by your institution. You can always create your own account using the self-service feature.
